    The Sustainability Action Plan was released on Earth Day, April 2019. Read the Plan

    *Targets reflect CO2 equivalence (CO2e).
    **2020 status refers to stormwater management areas that can absorb 90th percentile rainfall events.
    ***2026 and 2046 targets include the newly proposed Lake Campus that may include management of 95th percentile rain events.
    † Baseline established via GIS analysis.
    ‡ Includes soil reused in the past year or stored for later reuse on campus
    § Consumer items consist of recyclable paper, cardboard, glass, metal and plastic.
     Targets to be confirmed following campus waste study.
